Fw: tcp/ip question

Hi all,

I have three questions:

1-Which tcp port (or service) does iseries navigator program use to

transfer

to/from as400?
    In spite of  I close all tcp services except telnet I can still

transfer

data by this program.

2-We print on laser printers (which have ethernet,ip number) from as400.
   Which tcp port does an ip printer use? Or how can I find out?
   Bcs I want to close all tcp/udp ports except necessary ones.

3-We can print spool files on Hp3050 printer. But only 80 columns spool
files are printed properly.
    Spool files wider than 80 columns are cut from 80th column.What can I

do

about that?
    Printer type 3812 and it is attached to an outq has an ip number.

Thanks in advance,

Cevdet
